摘要:
A low power long range transceiver is presented. The transceiver includes: an antenna configured to receive an RF signal; an analog front-end circuit configured to receive the RF signal from the antenna and pre-condition the RF signal by at least one of amplify the RF signal, shift frequency of the RF signal and filter the RF signal; and a demodulator configured to receive the preconditioned signal from the front-end circuit and an assertion trigger signal signifying an end of a predefined time period, where the demodulator, in response to the assertion trigger signal, outputs a data value for a given data bit in the RF signal. A controller is also configured to receive the assertion trigger signal and, in response to the assertion trigger signal, disables at least one component of the transceiver, thereby reducing power consumption.
